Two weeks ago, when I danced in the new year a little too breathlessly, I decided to start improving my aerobic capacity, building muscle, and cutting way down on carbs, just like every resolution-making, pasta-loving schlub in America, the land of the gluten-free and the brave.

I located a self-help book, “Wheat Belly” by Dr. William Davis, whose title spoke directly to the last few years of my life, much of which has been spent reaching into restaurant bread baskets. Just envisioning the lean, strong, self-controlled person I am meant to be felt empowering. I got a hope buzz.

And someday I swear I will open that book, which sits waiting on the bathroom bookshelf on top of “You: The Owner’s Manual” by Drs. Michael F. Roizen
and Mehmet C. Oz. Someday I will turn my lard belly into a hard belly.

But like many of the millions who buy self-help books, in whose numbers “there is definitely a spike” after New Year’s Day, says Jim Milliot of Publishers Weekly, I will probably not change. Of the 45 percent of Americans who usually make New Year’s resolutions, according to StatisticBrain.com, only 8 percent are successful.

The hope buzz, though, is worth something. In the world of self-help books, just the promise of change, the mere possibility of becoming happy, fit, rich, and making someone fall in love with you in 90 minutes or less, is at a premium.

The healing begins and often ends with a visit to the bookstore or a download. “What a lot of people want when they go to self-help books is to just feel better,” says Jessica Lamb-Shapiro, author of a just-released look at self-help culture “Promise Land.” “And it doesn’t take that much to feel better. You feel better buying the book.”

In researching her book, Lamb-Shapiro, who blends the history of self-help with her quest to process her grief for her mother, bought 100 used self-help books. “I tended to find that the beginning was heavily annotated,” she says, “and the rest of the book didn’t look as though it had been touched.”

If Americans seeking self-help don’t tend to reach their goals, or even finish the books, they’re spending a lot of money on aspiration. According to a recent analysis of the self-improvement market by Marketdata Enterprises, a Tampa market research company, some $549 million a year is spent on self-help books in America, with diet books pulling in the most money. And “a significant portion of the buyers are repeat buyers.” says John LaRosa of Marketdata.

Self-help culture seems built for Americans; we did, after all, declare our right to the pursuit of happiness when we broke with Britain. Self-reliance, social mobility, individualism, the search for success and pleasure — our national ideologies parallel the goals of everything from Michael J. Losier’s “Law of Attraction” to Anthony Robbins’s “Awaken the Giant Within: How to Take Immediate Control of Your Mental, Emotional, Physical and Financial Destiny!” A particularly fierce American hunger for self-actualization grew out of the 1960s and flourished in the ’70s, promising to help us realize our human potential.

But self-help books existed long before this country, long before the Me Decade, as Lamb-Shapiro notes in “Promise Land”: Think ancient Egypt, where a genre called “Sebayt,” which means “teachings,” offered life coaching. Think Roman emperor Marcus Aurelius’s 12 books of “Meditations.” “The Victorians were also obsessed with self improvement,” Lamb-Shapiro says. One of their favorite books: the 1859 bestseller “Self-Help,” a collection of up-by-the-bootstraps stories by a Scot named, fittingly, Samuel Smiles that outsold its contemporary, “The Origin of Species.” The only book “Self-Help” didn’t outsell that year, Lamb-Shapiro notes, is the Bible, which is, in its own way,
a kind of self-help book.

There have long been vocal critics of the genre, including Wendy Kaminer, whose controversial “I’m Dysfunctional, You’re Dysfunctional” in 1992 addressed what she saw as the narcissism of the recovery movement. Among the most recent naysayers is Steve Salerno, author of the 2006 book “SHAM: How the Self-Help Movement Made America Helpless.”

Salerno says that self-help books offer an illusion of change that diverts people from making real change. “It helps people delude themselves into thinking, ‘Yeah, I’m doing something, I’m becoming a different person.’ But becoming a different person requires behavior changes, not just hope.”

Salerno singles out “The Secret,” the international bestseller about positive thinking that got a boost from Oprah. “You had so many people investing heavily in pure optimism for its own sake,” he says. “If I send the right vibes out into the universe, everything is going to change for me. In reality, why don’t you go back to school and earn yourself a degree, or learn a trade, or do something to change your life?”

Optimism as counterproductive? “Promise Land” also explores the less useful sides of positive thinking, as Lamb-Shapiro’s father was “relentlessly positive” and avoided talking about Lamb-Shapiro’s mother, who committed suicide when her daughter was 2.

“It can be extremely oppressive,” Lamb-Shapiro says, “if you’re feeling sad and somebody is hurling relentless optimism at you that isn’t acknowledging how you’re feeling. It’s great if whatever they say can turn you around and make you positive, but if it doesn’t work, you’re just left with your same feeling, and on top of that you’re feeling out of synch.

“It’s reasonable and common sense to understand that human life is full of ups and downs and life and death and marriage and divorce, and that if your feelings are all on the positive side, you’re not reacting to the full spectrum of human experience. I’m not against optimism, I just think there should be a balance.”

Lamb-Shapiro says she has noticed that self-help books reflect the values of the era when they were published. “During the Depression, there were . . . more books about getting rich than you’d find during times of prosperity. People do seem to write to the culture and the cultural needs of that moment. You could do a history of America by looking at what self-help books were popular at what time. The genre responds to people’s concerns and fears and desires.”

What, then, would be our current collective state of mind?

“Well, there does seem to be a gluten fear happening in the culture right now.”
